GREASE-CUP.

Application filed .Tune21, 1913.

To all whom it may concern:

Be it known that I, GEORGE W. BOWEN, of r-iuburn, in the county ofCayuga and State of New York, have invented a certain new and usefulGrease-Cup, of which the following is a specification.

This invention has for its object the production of a ratchet grease cupand particularly to constructions whereby the parts are compactlyarranged and the spring concealed; and the invention consists in thenovelcombinations and constructions hereinatter set forth and claimed.

in describing this invention reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is an elevation, partly broken away, showing the position ofthe parts when the cap occupies a position at nearly the limit of itsoutward or upward move ment.

Fig. 2 is a longitudinal sectional View illustrating the position of theparts when the cap is screwed downwardly and occupies a position betweenits extreme positions.

Figs. 3 and l are detail views of the base and the holding member.

This grease cup comprises generally a base, a cap turning on the base, anon-rotatable holding member slidably mounted on the base and coactingwith the cap to restrain turning thereof, and a spring located above theholding member and designed to pull upwardly thereon and hold the sameengaged with the cap, the holding member and the spring being sorelatively arranged that the spring is housed by the cap.

1 is the base which as here shown includes a head 2 and a stem 3depending from the head and terminating in a threaded nipple d by means01": which the base is attached in position in a hearing or other partto be lubricated. The stem 3 is also formed with an axial passage 5.

The head 2 is discoidal in general outline and is formed with a centralopening for receiving the upper end portion of the stem 3, which upperend portion 6 is reduced thereby forming a shoulder against which thehead 2 rests, and the projecting portion of the reduced portion 6 isriveted or spun on the upper face of the head 2, as indicated at 7.

8 is the cap threading on the head 2. The

cap may be of any suitable form, size and construction. 9 is the holdingor ratcheting member non-rotatably mounted on the stem 3 and slidablelengthwise thereof, the member 9 being opposed to the head 2; and 10 isthe spring interposed between the head and the holding or ratchetingmember 9 and connected to pull upwardly on the member 9 and hold thesame engaged with the cap 8 to hold the cap from turning.

The holding or ratcheting member 9 is discoidal in form and is formedwith a central opening for fitting the angular wrench hold portion 11 ofthe stem 3. One of the opposing parts 2 and 9 is formed with an annularflange inclosing the spring 10 when collapsed. As here shown both thehead 2 and member 9 are formed with annular flanges 12, 13 respectively,the flange 13 of the holding member being of sufficient diameter toinc-lose the head and its flange 12. The cap 8 and flange 13 areprovided with intercugaging means on their edges as ratchet teeth letand 15, and the holding member is formed with diametrically oppositefinger engaging lugs 16 by which said member can be pressed downwardlyagainst the action of the spring 10' to disengage the ratchet teeth whenit is desired to turn the cap 8 in a retrograde direction.

The spring 10 is of such form as to collapse into a plane and is hereshown as conical and coiled about the stem 3 and interposed between thehead 2 and holding mem ber 10, the larger end of the spring beingpreferably secured to the head 2 within the flange 12.

The opposite ends of the spring are connected respectively to the head 2and the holding member 9 by means of eyes 17 in the form of loops passedthrough slots in the parts 2 and 9 and having their ends 18 clenchedupon the outer faces of said parts 2 and 7. The eyes 17, associated withthe head 2, are located near the flange 12 while the eye associated withthe holding member 9 is located near the axial opening of said member.

In operation when the parts are in the position shown in Fig. 1, as whenthe cup is full of grease, the flanges 12 and 13 house the spring which,owing to the fact that it is conical, will collapse into a plane, and

when the parts are out of their position occupied in Fig. '1 and occupya position .110

such as shownin F ig, 2, the barrel portion of the cap 8 and the holdingmember S) house the spring.

What I claim is:

A grease cup comprising a base including a head and a stem dependingfrom the head, a cap threading on the head, a flat discoidal memberhaving an opening slidably fitting the stem and held from rotationthereon, said discoidal member having an upturned annular marginalflange extending toward the head, and of suiiicient diameter and widthto inclo'se thehead when the cap is removed, the flange being providedwith means at its edge for coacting with the lower edge of the 15 cap toresist turning of the cap, and a conical coil spring around the stem andconnected at one end to the head and at its other end to the discoidalmember.

In testimony whereof, I have hereunto signed my name in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this lth day of June, 1913.
